Description

A function to exploit base R's curve function. This returns a data.frame holding x and y values returned from a call to curve, but suppress the plotting of that function

Usage

gcurve(
  expr,
  from = NULL,
  to = NULL,
  n = 101,
  add = FALSE,
  type = "l",
  xname = "x",
  xlab = xname,
  ylab = NULL,
  log = NULL,
  xlim = NULL,
  category = NULL,
  ...
)

Arguments

expr	inherited from curve
from	inherited from curve
to	the range over which the function will be plotted.
n	inherited from curve
add	inherited from curve
type	inherited from curve
xname	inherited from curve
xlab	inherited from curve
ylab	inherited from curve
log	inherited from curve
xlim	inherited from curve
category	option to add a column populated with a factor (by gcurve)
...	inherited from curve
